skimage2.segmentation.mark_boundaries#

skimage2.segmentation.mark_boundaries(image, label_img, color=(1, 1, 0), outline_color=None, mode='outer', background_label=0)[source]#

Return image with boundaries between labeled regions highlighted.

Parameters:

imagendarray of shape (M, N[, 3]): Grayscale or RGB image.
label_imgndarray of shape (M, N) and dtype int: Label array where regions are marked by different integer values.
colorlength-3 sequence, optional: RGB color of boundaries in the output image.
outline_colorlength-3 sequence, optional: RGB color surrounding boundaries in the output image. If None, no outline is drawn.
modestring in {‘thick’, ‘inner’, ‘outer’, ‘subpixel’}, optional: The mode for finding boundaries.
background_labelint, optional: Which label to consider background (this is only useful for modes inner and outer).

Returns:

markedndarray of shape (M, N, 3) and dtype float: An image in which the boundaries between labels are superimposed on the original image.
